nilfs2: add missing return value kernel-doc descriptions

2025-01-25T06:47:25+00:00

There are a number of kernel-doc comments for functions that are missing return values, which also causes a number of warnings when the kernel-doc script is run with the "-Wall" option. Fix this issue by adding proper return value descriptions, and improve code maintainability.

nilfs2: convert persistent object allocator to be folio-based

2024-11-06T01:12:38+00:00

Regarding the persistent oject allocator, a common mechanism for allocating objects in metadata files such as inodes and DAT entries, convert the page-based implementation to a folio-based implementation. In this conversion, helper functions nilfs_palloc_group_desc_offset() and nilfs_palloc_bitmap_offset() are added and used to calculate the byte offset within a folio of a group descriptor structure and bitmap, respectively, to replace kmap_local_page with kmap_local_folio. In addition, a helper function called nilfs_palloc_entry_offset() is provided to facilitate common calculation of the byte offset within a folio of metadata file entries managed in the persistent object allocator format.

nilfs2: fix incorrect kernel-doc declaration of nilfs_palloc_req structure

2024-09-02T03:43:36+00:00

The "struct" keyword is missing from the kernel-doc comment of the nilfs_palloc_req structure, so add it to eliminate the following warning output by the kernel-doc script: fs/nilfs2/alloc.h:46: warning: cannot understand function prototype: 'struct nilfs_palloc_req ' Link: https://lkml.kernel.org/r/20240816074319.3253-5-konishi.ryusuke@gmail.com Signed-off-by: Ryusuke Konishi Signed-off-by: Andrew Morton

nilfs2: fix incorrect inode allocation from reserved inodes

2024-07-03T19:29:25+00:00

If the bitmap block that manages the inode allocation status is corrupted, nilfs_ifile_create_inode() may allocate a new inode from the reserved inode area where it should not be allocated. Previous fix commit d325dc6eb763 ("nilfs2: fix use-after-free bug of struct nilfs_root"), fixed the problem that reserved inodes with inode numbers less than NILFS_USER_INO (=11) were incorrectly reallocated due to bitmap corruption, but since the start number of non-reserved inodes is read from the super block and may change, in which case inode allocation may occur from the extended reserved inode area. If that happens, access to that inode will cause an IO error, causing the file system to degrade to an error state. Fix this potential issue by adding a wraparound option to the common metadata object allocation routine and by modifying nilfs_ifile_create_inode() to disable the option so that it only allocates inodes with inode numbers greater than or equal to the inode number read in "nilfs->ns_first_ino", regardless of the bitmap status of reserved inodes.
